Abstract

The invention relates to the technical field of environmental protection equipment, and discloses waste plastic recycling and granulating production equipment, which comprises an extruder, a hopper, amelting screw and an extrusion screw, two groups of sliding chutes and slideways are arranged at positions, corresponding to the upper part of the hopper, of the extruder, and the slideways are movably connected with an air cylinder through sliding blocks. According to the waste plastic recycling and granulating production equipment provided by the invention, when molten plastic rotates and movesalong with the extrusion screw, the two filtering pieces are inserted into a groove of the extrusion screw in turn to filter out incompletely molten plastic or impurities, so that the purity of meltis improved, and the quality of regenerated plastic is improved; and secondly, plastic on the inner wall of a hopper body is extruded through airflow generated when the air cylinder moves, one side ofthe plastic where bridging occurs is suspended, movement of plastic fragments in the hopper is assisted, then disturbance of the plastic fragments can be increased through rapid pulse airflow, the bridging probability is further reduced, the conveying speed of the broken fragments is increased, so that the conveying speed is matched with the processing speed of a granulator.

Description

technical field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to waste plastic recycling and granulation production equipment. Background technique

[0002] Due to the wide range of sources and complex components of recycled plastics, they need to be broken and cleaned before they are formally formed and granulated. The broken plastics after cleaning and drying are transported to the granulator through the conveying device, extruded by the granulator and pelletized to produce Plastic granules that can be directly used by plastic companies.

[0003] There are thousands of common plastics in life, and different plastics have different uses. Recycled plastics are usually mixed with other types of plastics. When recycling plastics, the plastic components are relatively single, but in the separation process It is very difficult to achieve complete separation. Because the melting point temperature of different plastics is...
